[R] Is 'history' recorded in Rscript?

[Peng Yu]

Hi,

I got the following error. Does it mean that the files in the save
session will not be saved in history in Rscript?

$ Rscript savehistory.R
> f=tempfile()
> f
[1] "/tmp/RtmpMEGKVq/file327b23c6"
> savehistory(f)
Error in savehistory(file) : no history available to save
Execution halted

Regards,
Peng
